This information about the pupolations of these birds provides the crucial information that is necessary for national and international conservation policies. It shows what governments of range states need to do to meet their international obligations, for instance the policies of the African Eurasian Waterbird Agreement (AEWA).

For each species, the most appropriate flyway boundaries are discussed and plotted on maps. Maps also show all potential and actual key-sites, and breeding ranges for migratory species. Key-sites are also presented in table form, with justification for all flyway population estimate and boundary changes.
